The Bluetooth quizzing application consists of a server and client mobile Android application. It will utilize a queuing system to allow many clients to connect simultaneously to the server. When clients connect, they can register or choose the option to complete a quiz that the lecturer selected. Results are automatically sent when quiz is done from the client application. Data analysis can then be done to review the progress of students.

The mobile device manufacturers and Internet Of Things are searching for more compatible and easy to connect protocols that increase coverage, which generates the user an effective experience when using different devices. Nevertheless, the constant updating process opens a security gap that exposes the users' personal information. Bluetooth is a communication protocol openly used by manufacturers because of their excellent information transfer capacities, allowing hackers to exploit it. The manufacturers work daily, generating security patches for communication protocols but this hasn't been enough to mitigate vulnerabilities. The security has always been on the manufacturer's side but the final user is limited to use a few security customization options to protect his network perimeter. Based on the wireless devices' background we wonder, Is there any way in which the user has the chance to reduce the possible dangers that wireless devices face? We can answer this q...

Design and implementation of an FPGA based system is illustrated in this paper.

The capability of the fabricated device to send data via Bluetooth which meanwhile uses an special protocol to encrypt data transmit as well as incorporated error detection and correction protocol makes the device capable to be utilized in places demand ultrahigh immune approach. The Device is also capable to communicate with the computer and store the obtained information. To evaluate the performance of the proposed circuit the system is first simulated in Matlab and then it is implemented in logical gate level at Xilinx ISE environment and finally is practically implemented by Xilinx SPARTAN 3 FPGA and its performance is evaluated experimentally.

There is increasing interest in wireless ad hoc networks built from portable devices equipped with short-range wireless network interfaces. This paper addresses issues related to internetworking such networks to form larger "scatternets." Within the constraints imposed by the emerging standard Bluetooth link layer and MAC protocol, we describe an efficient online topology formation algorithm, called TSF (Tree Scatternet Formation) to build scatternets. TSF connects nodes in a tree structure that simplifies packet routing and scheduling. The design allows nodes to arrive and leave arbitrarily, incrementally building the topology and healing partitions when they occur. We present simulation results that show that TSF has low tree formation latency and also generates an efficient topology for forwarding packets.

In this paper we present a distributed positioning system for indoor environments based on a network of compact independent anchor nodes operating as specialized WiFi access points. Each node is built with component-off-the-shelves and it is capable of standard IEEE 802.11 connectivity at 2.45 GHz. The enabling technology for the localization is the Switched Beam Antenna (SBA) equipped in each node, which permits a space division multiple access at network-level. The positional information is the result of a maximum likeli hood estimation driven by the expected signal space partition of the constellation, and it is tolerant to noisy power measurements, such as Received Signal Strength Indicator, thanks to angular filtering capability of the SBA, which in addition operates in circular polarization. Experimental validations demonstrate the performance of a 3-anchors network, operating within the IEEE 802.11 protocol, monitoring a single nomadic node inside a 7 m 2 indoor square area. It results that 68% of the square area is covered with a localization error below 50 cm, with a mean error of 47 cm. Inside the triangular mesh defined by the three anchors, the mean error drops to 39cm, with 88% of the area being below 50 cm. In addition, the maximum error is always below 77 cm.

A rush forward of research activities in wireless communication has been seen in last decade. There are new points of view on how to communicate effectively over wireless channels from this research drive. The purpose or aim of this paper is to study the basics as well as new research developments.

A novel and compact tri-band planar antenna for 2.4/5.2/5.8-GHz wireless local area network (WLAN), 2.3/3.5/5.5-GHz Worldwide Interoperability for Microwave Access (WiMAX) and Bluetooth applications is proposed and studied in this paper. The antenna comprises of a L-shaped element which is coupled with a ground shorted parasitic resonator to generate three resonant modes for tri-band operation. The L-shaped element which is placed on top of the substrate is fed by a 50Ω microstrip feed line and is responsible for the generation of a wide band at 5.5 GHz. The parasitic resonator is placed on the other side of the substrate and is directly connected to the ground plane. The presence of the parasitic resonator gives rise to two additional resonant bands at 2.3 GHz and 3.5 GHz. Thus, together the two elements generate three resonant bands to cover WLAN, WiMAX and Bluetooth bands of operation. A thorough parametric study has been performed on the antenna and it has been found that the three bands can be tuned by varying certain dimensions of the antenna. Hence, the same design can be used for frequencies in adjacent bands as well with minor changes in its dimensions. Important antenna parameters such as return loss, radiation pattern and peak gains in the operating bands have been studied in detail to prove that the proposed design is a promising candidate for the aforementioned wireless technologies.

Compression bandages are specially designed to apply pressure, helping to maintain blood flow and reduce discomfort and swelling. Compression bandages are a simple non-invasive treatment for varicose veins, chronic venous insufficiency and lymph edema. The treatment compresses superficial veins to promote the flow of blood through the body veins. The main objective is to design pressure sensing bandage using suitable method and to measure different level of pressure intensity. Compression bandages come in a variety of sizes, length, and colors. They are also available with different strengths of compression. Stockings and compression bandages with successive sensors are available in the market but there provide least comfort and hence make them difficult to be worn. Further, these sensors often have contact with skin which makes them undesirable. In order to overcome this level we have to design the bandages with using compressed air concepts. The main objective is to design pressure sensing fabric using suitable method and to measure different level of pressure. These different readings of pressure will be sent through wireless Bluetooth device which connects the patients' device to the concerned.

It is a vital importance to determine defective bearings during the rotation of the power generating and power consuming machines without reaching the critical level. In this study; an experimental setup was created, and a Condition Monitoring Application (CMA) was performed in the laboratory environment which could monitor vibration, temperature, acoustic emission (AE), current and revolution measurements for ORS 6203 type defective bearing detection. In the designed test setup, a microcontroller platform used as a system brain, a direct current machine with a shaft mounted bearing, and miscellaneous sensors used such as 3-axis accelerometer that senses vibrations, a hall sensor module for revolution measure, a microphone module for AE detection, current and voltage sensor modules for power consumption measurement, contactless temperature sensor module for temperature measurement. CMA has been designed for monitoring of system via Bluetooth module. With the help of the microcontroller platform, the data collected from the sensors is transmitted wirelessly to the Android smartphone to be plotted and recorded. After the data exceeds certain thresholds, the control system is able to provide SMS and/or e-mail notification to the related maintenance team with the Android smartphone. Linear Discriminant Analysis (LDA), Random Forest (RF), Support Vector Machine (SVM), k-Nearest Neighbor (kNN), and Decision Tree (DT) algorithms applied to the collected data and models were created. As a result of accuracy analysis over %96 success was achieved for all models.
